Hyundai plans to spend $15 million on the facility and other upgrades. Plans for the expansion were announced at the North American International Auto Show in Detroit. The facility will be built at the South Korean automaker's Hyundai America Technical Center in Washtenaw County's Superior Township, near Ann Arbor.

To secure the deal, the state agreed to spend $2.5 million to build a power substation to improve service to the testing facility. The funding involves Superior Township and is similar to a loan.
